I'm actually in the process of writing a guide for Uno which will make things much clearer.
I'm also releasing a simple DB15 hat which will dock to the USB Shield PCB which in turn docks to the Uno.
To answer your question quickly, all you need is an Uno board and a USB Host Shield board (which docks to the top of the Uno). If you want to wire it into an actual supergun you'll need some patch wires and a female DB15 connector. This last step is optional if you just want to test as you can see what's happening in the serial monitor of the Arduino IDE.
No other passive components are required.
The custom PCB will get some updates next week and the size will down signify. About the all in one, i think it's already tiny for the all the circuit it's handling.Any way to get the size down eventually? If it hangs out to far will the weight added with a cord connected be a concern?
Please, update your Arduino IDE and if you still need help, visit our Discord.when I try to upload the file to my arduino UNO, Arduino IDE said "collect2.exe: error: ld returned 1 exit status".
Really kind article! Thanks retroRGB staff!There is a nice article about your fantastic work on RetroRGB:
